ROLLING-MILL FEED MECHANISM.

SPECIFICATION forming part of Letters Patent No. 789,298, dated May 9, 1905.

Application filed July 13,1903. Serial No. 165,213.

To all whont it may concern.-

Be it known that I, EDWIN E. SLICK, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Itolling-Mill Feed Mechanism, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure lis a vertical longitudinal section showing one form of feed mechanism constructed in accordance with my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a top plan view showing another form of the invention with vertical rollers. Fig. 4 is a front elevation of the form of Fig. 3, and Fig. 5 is a side elevation of the same.

My invention relates to the feeding of metal toward and from the rolls of a rollingmill, and is designed to do away with ordinary roller-tables and provide an improved pinch-roller system by which the metal may be positively fed in either direction away from the rolls or toward the rolls.

To that end it consists in providing a pair of feeding-rollers which are continuously driven in opposite directions, in combination. with a mating pair of pinch-rollers arranged so that the metal may be forced against either of the driven rollers as desired, according to the direction in which the metal is to be fed.

It further consists in providing a tilting frame for the pinch-rollers and in the construction and arrangement of the parts, as hereinafter more fully described and claimed.

In the drawings, referring to the form of Fig. 1, 2 2 represent a pair of horizontal feeding-rollers arranged side by side, their shafts being carried in suitable bearings of end housings 3 3. The shafts of both rollers are extended at one end and carry intermeshing gear-wheels 4 4, and the shaft of one of the rollers is extended to receive a coupling 5, by which both rollers are continuously rotated in opposite directions.

The housings are preferably of A shape, and in their upper parts have suitable bearings for a rock-shaft 6, which is actuated by a lever 7, which may be moved by hand or by power connections.

The intermediate portion of the shaft 6 is provided with two cross-heads 8 8, between which are pivoted the side shafts 9 9, having pinch-rollers 10 1O loosely mounted thereon. In using the device it is placed in line with the exit-pass of the rolls and at a suitable distance therefrom, preferably such a dis tance that the metal will pass between the rollers 10 before it leaves the rolls of the mill. As the front end of the metal. passes between the feeding-rollers 2 and the pinch-rollers 10 the levers 7 may be rocked, so as to pinch the metal against the roller, which is rotating in the proper direction to assist the metal and feed it forwardly. To return the metal to the rolling-mill, the lovers rock in the opposite direction, when the piece will be pinched or forced against the other feeding-roller, which. will feed it back to the rolls.

In Figs. 3, 4, and 5 I show another form of the invention, wherein the rollers are placed vertically, so that the metal may drop between them. In this form therollers 2 are secured at the upper ends of vertical shafts 11, which shafts are provided at their lower ends with bevel-wheels 12, inter-meshing with beveled wheels 13 upon a driving-shaft 14. This shaft 14 is mounted in suitable hearings in the base 15 of the framework. The A- shaped frame 3 projects horizontally below the rollers 2 and in its apeX is mounted a vertical shaft 6, having a lever 7, by which it is rocked. The shaft 6 carries the horizontal cr0sshead 8, between which the pinch-rollers 10 are pivotally mounted as before. The operation of this second form is substantially the same as the first form, the metal passing between the two sets of rollers or dropping down between them and being fed in the desired direction by forcing it against one of the driven feed-rollers.

The advantages of my invention result from using a pair of driven feed-rollers constantly rotating in opposite directions in connection with the pinch-rollers, and means for moving either one of these pinch-rollers to support the metal. against one of the driven rollers. The use of reversing engine or clutch is rendered unnecessary, and the device is simple and easily operated.

Many variations may be made in the form each mating with a feed-roller and arranged to receive the issuing metal between them, and mechanism for forcing each pinch-roller toward its feed-roller; substantially as described.

2. Feed mechanism for rolling-mills comprising a pair of plain-faced feed-rollers arranged side by side, mechanism for driving said rollers in opposite directions, a: tilting support having a pair of pinch-rollers each mating with one of the feed-rollers, each feedroller and pinch-roller being arranged to receive the issuing metal between them, and means for rocking the tilting support; substantially as described.

In testimony whereof I have hereunto set my hand.
